FOURTH-POINT SUPPORT FOR BRAKE-BEAMS.

Specification of Letters Patent.

Patented Nov. 2, E920.

Application filed June 9, 1919. Serial No. 302,797.

I! '0 ct whom it may concern:

Be it known that I, Crninnns I'IAINES WIL- Lmtrs, a citizen of the United States, residing at the city of Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Fourth-Point Supports for BrakeBeams, of. which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to maize and use the same, reference being had to the accompanying drawings, forming part of this specification, in whiel1 Figure 1 is a side elevational View of my improved fourth point support for brake beams, and

Fig. 2 is a plan View showing the support as used on either side of the beam.

This invention relates to a new and useful improvement in fourth point supports for brake beams, and is designed particularly to beapplied to brake beams in common I use, the object being to utilize a single casting for the members constituting the support, and which casting may be applied at either end of the beam, thus making the support reversible. It has been found in practice that inexperienced repair men do not correctly apply the fourth point support to brake beams where they are made for application to the right and left hand sides of the beam. I, therefore, propose to overcome this dilliciiilty by making a single casting which, when assembled with its companion and a wearing surface, permits of the application of the support either on the right or left hand side, as occasion requires.

In the drawings, 1 indicates the spring plank of the truck and 2 the inclined supporting track for'the fourth point support. is a compression member of a brake beam and 4 the tension member thereof. 5 is the brake head, which may be of any usual construction, and 6 is the brake hanger.

7 is a casting formed with seats at its extremities to embrace the compression and tension members, these seats being anticlinal, as shown, so that a casting may be applied, top or bottom, at either side of the beam. This casting is provided with a strengthening rib S and a hollow boss 9, which latter is resigned to receive a fastening means in the form of a bolt 10. lhe bolt 10 is also employed to secure a rubbing surface on the under face of the lower one of the pair of castings, said rubbing surface being preferably semispherical and being provided with a socket to receive the head of the bolt 10. The semispherical rubbing surface is indicated at 11.

What I claim is:

1. A reversible fourth point support for brake beams in the form of a casting having anticlinal seats for the compression and tension members of the beam located at each end of said casting.

2. A reversible fourth point support for brake beams composed of a pair of like members having oppositely inclined seats at their ends in combination with fastening means for securing said members together.

3. A reversible fourth point support for brake beams comprising like members having anticlinal seats at their opposite ends, fastening means for securing said members together on the beam, and a rubbing surface held in position on one of said members by said fastening means.

In testimony whereof I signature this 3rd day of CHARLES HAINES WILLIAMS.

hereunto my June, 1919.
